This invention relates to a padlock of the kind, in` whichtwo tubular members or a tubular member yand a rodlike member embrace each other and are secured by a spring lockv .enclosed within sai-d parts in such a manner that unlocking can only be performed by a key. j

According to my invention, locking of the parts isperformed by means oflatches arranged in one of the two cooperating lock members and provided with locking faces adapted to embrace a cross-piece or fore lock arranged in the'second lock member and toy grip suitable keepers `or staples. Further particulars ofthe invention will be seen c from the following detailed description.

` In the accompanying ydrawing I haveillustrated two different embodiments'of my invention.

AFig. 1 shows one embodiment of the lockl in frontview.`

Figs. 2 and 3 show' a. modilication of they lock in twovertical sections at a right angle with respectl toeach other.

Figs. and 5 show respectively one of thel locking elements in plan View. Fig. 6 is a section along line A-B of Fig.

3, seen from below.

F 7 is a section along line A-B yof Fig. 3, seen from above. `Fig. 8 shows a detail.

The4 lock consistsof two tubularl pieces,

which will hereinafter be referred toas bolt piece 1' and locking element 6 respectively. lBoth elements may be arranged so as to slide within ears which are fastened in both leaves of a folding or sliding door and project therefrom at right angles, the yloop of the 'ear lying vertically so as to allow the bolt piece to perform a lateral sliding move-k ment through it. In each door leaf there is at least one ear for carrying the elements 1 y and 6 oralternatively the arrangement may be such that only one of the tube shaped lock elements isslidable whereas-the other l isrigidly fastened to one of the leaves. The

"length of bolt piece 1 corresponds'to the ,distance between the ears *fastened in the f door as shown in Fig. 1. In order to limit .the sliding movement throughy the. ears'the Ybolt-piece is at one of its ends provided with `a cylindrical head2 of larger diameter, the l outer edge of the casing'being rounded. In

the embodiment of the device shown in Figures 2 and 3 the head contains at the bottom a' spring 3 and a buffer plate 4, while in the embodiment illustrated in Fig. l1 the said element 6, is likewise tube-shaped and also vcarries at one of its ends a head 7 larger in diameter than the tube proper in which a" lock is located preferably of the cylindel` type. It consists of a cylinderl 8 which can only beturned after vthe combination elements 9 have been brought into a certain position by means of a key l0. The cylinder 8 is provided with a projecting portion 11 whichl upon rotation of the key lO'operates two actuating members 15 and 16 pivotally mounted on a base plate 12 by means 'of screws 13 andy 14; the said actuating members serve for compressing the rear ends 18 of latches kept apart by means of a spring y 17. 'The said latches form a tongue andare provided with eyes 20 encircling a pin 21 fastened in the locking element 6 at a right angle with respect to the longitudinal axis thereof; at the inside of the front ends of the latches there are incisions 22 the size of each of which is half the size of the crosssection of the cross piece 5. In front of the incisions, the front ends of the latches are provided with rounded edges 19directed outwardly and forwardly, with respect to Athe center of the locking device.

In the position of rest inv which the rear ends 18 of the latches are pressed apart from each f other by meansof the spring 17, the said latches engage by means of shoulders 23 with projections 24. which form keepers on the locking piece 6. The tubular Wall of the locking element 6 is provided with recesses 25 for accommodatingtthe latches and slots 26 for the cross-piece 5. The two yactuating members 15 and 16 are connected by means of a link 27 V(Fig. 7), so that when member 16 is rocked by the projection 11 themember 15 is at the same time rocked to the opposite side. The arms of theactuating members are pressing upon the respective rear ends 18 of the latches which are held apart by the spring 17 and the rear ends ot' the latches are thus moved towards each other Whereas at the same time the front ends 19 ot kthe latches are pressed apart. The head 7 is closed at its open end by means of a sheet or covering plate 30 which. is held .at its place by means of a divided ring 31, Which enters recesses 32m the side Wall of lthe head and annular recesses providedk inthe cover plate 30 and in the base plate 12 of the lock. Said base plate is secured to the cover plate by meansot small .screws 33 with countersunk heads arranged atfsuch a distance from the longitudinal axis of the lock that they will be half covered or fully covered by the front edge oit the bolt element 1 when this element is in'i'ts locking position. This method of inserting the base 'plate will allow easy mounting and removal of all the partswhile presenting no surface or part Which could `easily be attached by any one attempting to force the lock, as only a smooth and uninterrupted surface, not present-ing any point ol attack to any tool (with the sole exception of the key hole) is'accessible at the outside of the lock.

In actual use the locking element 6 is Vpushed into the bolt-piece l; While this is done the latch ends 18 slide With the inclined ifaces of their shoulders 23 along the inclined :faces oli the projections 24 off the locking element the ends 18 being moved towards each other whereas ends r19 are receding which action is lcompleted as soon as 'the inclined faces ot' their edges reach the cross-` piece 5 Which is embraced by the. incisions 22 yWhile the ends 19 are again pressed together by the action of yspring 17.

The lock can only be opened by means loi key 10, by which the cylinder 8 and the projection 11 are rotated to relieve the crosspiece `5 from the locking action oit the latches. The butter plate 4 with its spring 3 which is put under tension When the locking elen ment 6 is completely introduced facilitate withdrawing of the locking element 6 from the bolt piece l, .spring 3 being released thereby and pressing on the front edge of the locking element 6. The cylinder lock may be of any approved type and may especially be constructed in such a Way that thel key 10 can only be Withdrawn in the loose position of the lock.
